BSP742RINT Equivalent & Substitute Parts

Part Overview

The BSP742RINT is a Power Management IC (PMIC) classified as a power switch/driver manufactured by Infineon Technologies. It functions as a 1:1 N-Channel high-side switch with 400mA output capability, designed for general-purpose switching applications in automotive-grade systems. The BSP742RINT is currently listed as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The BSP742RINT has one parametric equivalent substitute: BSP742RIXUMA1. This substitution is valid based on the following matching electrical and mechanical parameters:

• Identical output configuration (1:1 N-Channel high-side switch)
• Identical maximum output current (400mA)
• Identical on-resistance specification (250mOhm typical)
• Identical load voltage range (5V ~ 34V)
• Identical operating temperature range (-40°C ~ 150°C)
• Identical package form factor (8-SOIC, 0.154" width)
• Identical surface mount mounting type
• Identical fault protection features (Current Limiting, Over Temperature, Over Voltage)
• Same base product number (BSP742)

The primary distinction is product status: BSP742RIXUMA1 is active and in high-volume production, whereas BSP742RINT is obsolete. Both parts belong to Infineon's miniPROFET® series and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

BSP742RIXUMA1 is the direct substitute for BSP742RINT based on complete electrical and mechanical parameter alignment. The obsolescence of BSP742RINT necessitates migration to BSP742RIXUMA1 for new designs and ongoing production support.

BSP742RIXUMA1 offers the following advantages for component selection:

• Active product status with high-volume availability (60,100 pcs in stock versus 796 pcs for obsolete BSP742RINT)
• ROHS3 compliance certification
• EAR99 export classification versus obsolete designation
• Identical electrical performance and package footprint
• Maintained within Infineon's miniPROFET® product line

For applications requiring automotive-grade qualification (AEC-Q100), verify that BSP742RIXUMA1 meets your specific qualification requirements, as this certification status is not explicitly stated in the substitute part data.

Frequently Asked Questions (FAQ)

Q: Can BSP742RIXUMA1 directly replace BSP742RINT in existing designs?

A: Yes. Both parts share identical electrical specifications (400mA output, 250mOhm Rds On, 5V–34V load voltage range), identical fault protection features, and identical 8-SOIC package geometry. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: BSP742RINT is obsolete. BSP742RIXUMA1 is the active equivalent from Infineon Technologies with full parameter compatibility.

Q: Are there packaging differences between these parts?

A: Both parts use 8-SOIC (0.154", 3.90mm width) surface mount packages. BSP742RIXUMA1 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, whereas BSP742RINT packaging format is not specified.

Q: What compliance certifications apply to BSP742RIXUMA1?

A: BSP742RIXUMA1 is ROHS3 compliant and carries EAR99 export classification. Automotive-grade (AEC-Q100) certification status for BSP742RIXUMA1 is not documented in the provided specifications.

Q: Are the thermal and operating conditions identical?

A: Yes. Both parts operate across -40°C to 150°C junction temperature range and maintain identical moisture sensitivity levels (MSL 3, 168 hours).
